To all whom t may concern.'

lBe it known that I, RICHARD T. NEWTON,

.to provide means arranged on the dash of the car or in other convenient position with-A in easy vision of the driver, by which he can see at a lancethe condition of thel liquid level in t e tanks. l vIn the accompanying drawings Figure 1 is a partial section through the hood at the front end of the car showin a connection from thel radiator jacket tothe 1ndicator on the dash, and associated parts.

Fig. 2 is a vertical section, to enlarged scale, of the indicator bracket.

Fig. 3 isa sectiony on the line 3 3, Fig. 2. Fig. 4 is a vertical section, on the line 44,

and its supporting Fig. 5, through the gravity operated valve.

arran ed in the a epi in Figig is a seciigio on Eheglne 5 5, Fig. 4. Fig. 6 is a view similar to Fig. 4, but showingA a modified construction' of the gravity controlled valve.

Fig. 7 is a side elevation of another modication of the gravity valve.

8 and 9 are sections on the lines 8-8, g. 10 isf a vertical sectlon through the gasolene tank valve. j

Fig. 11 is a section on the line 11- 11,

f ig. 1 2is a front elevation of a twin ga'ge arrangement for both tanks, andl Fig. 13 isfa side elevation thereof.

j It is highlydesirable that the driver of an automobile, should have `Within' ,easy vi'- -the condition oijzhis fuel supply in the gasolene tank and also the 4 ing liquid in the radiator tank 4and preferably also a thermostat showing the temperature of th latter.

ile indicating gages for |'the gasolene tanks .have been prevlously `suggested they.

have` not gone into extensive use'partially because of-their more or less expensive construction, and partially because of their decient operation. Moreover, so far as I am exact, I have provided a the piping when arranged in the casting aware there has never heretofore been pro- -vided a radiator tank indicator or gage at the dash of the car nor a thermostat associated therewith. By the present invention I have provided indicator means for4 bothl tanks arranged at the dash and preferably associated l th'lggemperature .of the water in the radiator ta In Fig. l, I have shown the engine hood 2O in section to disclose the radiator jacket 21which surrounds the cylinders. Onthe dash 22 is mounted the `gage 24 connected at its lower end by piping 25 to the lower portion of the radiator tank. Inasmuch as the position of the radiator may varyWith-Ielation to the dash.

in cars of diierent makes, I prefer to make the bracket of the'construction shown in Fig. 2 and comprising a vertical slideway 26 embraced by the'lugs 27 of the gage plate 28 and secured in adjusted position by the clamping screws 29.- By vertically adjusting the gage the level of the liquid therein can be properly related to the graduations on thek plate 28 when the radiator tank is full.

Inasmuch as the liquid flows directly from the radiatorjacket to the gage and thus establishes direct the same, it is obvious that when the car is on agrade the variation of the liquid level in the tank will affect the liquid in the gage 'glass and cause thelatter to register incorrectly. In order to maintain the gage level valve device arranged in v,thepipingl25 bef4 tween-the radiator j'a'cket and the gage'and serving to stop the flow. of* liquid through the 'car is on a predetermined grade sufficient to substantially affect the reading 'of the gage. As shown in Figs. 4 and 5l the weight device forcontrolllng the valve'isshoyvn as a pendulum. The valve is piping 25 andpierced y an offset iuid pasa bracket 23. carrying Patented June 21, 1921.

with the thermostat to disclose so l weight actuated Y 30 coupled with the f sage 31 in'which is'formed the valve seat 32.`

Coperatingwith the valve seat is a' cone valve 33. formed at 'the end of a vertically arranged valve stem 34. VThe enlargedhead 35 of the valve stem rests against the head 36 of a pendulum 37 givvoted at 38"'to lugs 39 on the casting 30. hen the car 1s level the head 35 of the valve rests flat against the head 36 ofthe pendulum as shown. But

when the car 1s on 'a 'grade the pendulumv 4E5' The ga the car again reaches the level and thegage by setting the valve att 20 more sensitive valveconstruction. Instead- '25' 45 to the lever.

g Lacasse con'stant irrespective of the displacement of .the liquid in the radiator. On the return of -the car to level the cam surfaces 53 and 54 coperate to lift the valve stem and again establish communication between the radiator and gage.

'The fact that directly vto the ge at the dash, enables me to combine with the' gage a thermometric'device lofany suitable Asort to indicate the temperature of .thenliquid in4 thetank. Thus a bay 58 may bel formed in the coupling 59 fat the bottom of the gage glass thermometer 60 secured in gle tothe valve stem and lifts .the latter with a cam action thus closing thevvalve vand'- reventing the flow-.lof liquid from the tan to the gage.

Com-I .munication between the gage and the tank is at oncetrestablished automatically when takes a positionf at an an readin 1s at once corrected automatically to'indicate the liquid levelv in the radiator at that tine. The sensitiv'eness of the valve to grade Amay be made asl fine as requisite e necessary distance. fromthe valve seat an by predetermining ,the length of the cross heads on the valve stein andpendulum.

In Fig. 6, I have illustrated another and and a with its bulb dipping into the bay, cate the temperature of `the liquid.

Under certain conditions where the fuel tank 'islocated'at a suiicient height with -reto indiof the` resent type for indicating the liqiliid of a single yalve- I provide a pair of'. .valves level t erein at theldash. Where sucv a 40 and 41 restin on lthe-opposite ends ofthe cross head 42o the niS oted pendulum lever. 43. The-pendulum', weight 44'is jointed yat -When the car is level both valve's are openbut vwhen vthecarreachespredetermined grade one -or the other of the valves is closed as the lever 43 swings on its pivot. The -jointingof the. weight to of the nature of the feed of the fuel to the carbureterto take care of J fuel tank. Where such is caseit is desirable to` counterbalance the pressure on both sides of the liquid in the gage by establishing a connection fromthe .topo

X to the fuel the 'radiator liquid is "ledpressure in the the position -v lation tothe dash it is possible to use a gage gage -is usedit may be necessary by reason the, lever at'45 `serves to prevent sudden 'actank. v I have indicated inl dotted -lines in tuation of the lever 43 due to inertia or sud- Fig. 1 such a"'connection to the radiator, den 'starting or stopping of the car land `where thisarrangement may also beof value moreover 'relieves the valve parts of un. at times-in view of the fact that the cooling"v i ,necessary wear and strain; Stops 46 on the pendulumv casing limit the sway of/the heated to generate steam.
